Abstract: Der Erfindung liegt die Aufgabe zugrunde, bei einem Funknetz 
mit mobilen und stationären Funksende- und -empfangsstationen, 
die je einen Auswerter für die jeweilige Empfangsqualität 
aufweisen, die Gleichkanal-, Nachbarkanal- und Interkanalmodu­
lationsstörungen mit geringerem Aufwand zu reduzieren. Dabei 
soll auf eine aufwendige zentrale Auswertung bekannter Funk­

     Die Aufgabe wird bei einem gattungsgemäßen Funknetz dadurch 
gelöst, daß jede Funksende- und -empfangsstation (10, 11) die 
Empfangsqualität bei bestehender Funkverbindung mittels des 
Auswerters überwacht. Wird ein vorgegebener unterer Grenzwert 
der Empfangsqualität unterschritten, so wird automatisch die 
Sendeleistung erhöht; umgekehrt wird bei einer Überschreitung 
eines vorgegebenen oberen Grenzwertes der Empfangsqualität die 
Sendeleistung wieder reduziert.  
     Die Erfindung eignet sich insbesondere für Funknetze mit 
zellularer Aufteilung des Funkgebietes.

Patent EP-0364955-A3 (EP)
Title: A label-switching and control interface for asynchronous fast-packet switching
IPC: H04L12/56
Filed: 1989-10-17
Abstract: A label-switching and control interface for asynchronous 
fast-packet switching consisting of a set of label-switching and cell-­
processing units controlled by a suitable control unit; said units 
operate at each multiplex level in real time thanks to a 
microprogrammed logic requiring the control processor intervention 
only at the connection set-up/release. Said units implement the low 
levels of the flow control algorithms necessary to conveniently 
exploit the advantages of said techniques. The label becomes 
indicative of a virtual circuit which is allotted only locally to the 
call, annulling thus the necessity of very extensive labels, while the 
parameters which characterize the connection which uses a particular 
label are stored in the unit itself. Each unit switches the label 
characterizing the connection on the node input multiplex, with that 
whereby it is characterized on the output multiplex and at the same 
time associates, with each cell, the information necessary to 
multiplex switching which is then carried out in a self-routing 
network; the cells processed in this way by each unit of the set are 
statistically multiplexed ifl an asynchronous way and sent to a 
connection network termination. Such a termination serves more 
asynchronous multiplexes, which can be at different frequency from 
each other and more particulary it is worth noticing that each label 
switching unit hasn't its own operating frequency, but automatically 
takes up that of the asynchronous multiplex it is connected to.

Title: Self routing packet switching network architecture
IPC: H04L12/56
Filed: 1989-12-12
Abstract: A network architecture of the sort-then-expand type for routing packets including 
destination information is disclosed. The network includes a distribution stage 
comprising a plurality of input sort units, an intermediate stage comprising a 
plurality of intermediate sort units and an output stage comprising a plurality of

intermediate sort units such that each intermediate sort unit receives approximately 
the same number of packets destined for each output switch as the other intermediate 
sort units. Each intermediate sort unit identifies packet groups for a common output 
switch and connects the groups to the destination output switch. Each destination 
output switch merges the received groups of packets and distributes them to output 
ports.

Title: Magnetic recording and reproducing apparatus and method of recording and reproducing
IPC: G11B27/28
Filed: 1989-12-12
Abstract: A magnetic recording and reproducing apparatus 
records audio signals digitized by rotary heads (9, 10) on 
a magnetic tape (12), and reproduces the recorded audio 
signals. Clock signals and time code data are extracted 
from externally inputted time code signals by means of a 
demodulating circuit (72), and phase difference between 
the frame clock signals and the reference signal is 
detected by a phase difference detecting circuit (74). A 
microcomputer (23) assigns the phase difference 
information and the time code data to sub code packs and 
stores the same in the memory circuit (40). The stored 
phase difference information and the time code data are 
recorded on the magnetic tape. In reproduction, the 
microcomputer outputs the original time code signals 
responsive to the reproduced phase difference information 
and the time code data.

Title: Semiconductor memory circuit
IPC: H01L21/8246
Filed: 1989-02-08
Abstract: A semiconductor memory circuit comprises a plu­
rality of memory cells (M11 - M22) and a plurality of 
programming transistors (1), each memory cell being 
provided at the intersections of one bit line (BL1 - 
BL3) and one word line (WL1 - WL3). The memory cell 
includes an insulator (2) and a cell transistor (3), and 
a conductivity type of the cell transistor selected by a 
word line select signal is opposite to that of the 
programming transistor selected by a bit line select 
signal (Vin). The memory cell is programmed by 
utilizing an electrical breakdown of the insulator, when 
the bit line select signal and the word line select 
signal supplied are in-phase and both the programming 
transistor and the cell transistor are switched. 
Therefore, the memory cell is programmed in a short time 
during which the programming transistor and the cell 
transistor are switched, and thus this semiconductor 
memory circuit can be programmed with a low consumption 
of power and of a high speed.
